4 Port Audio Switch, 3.5mm Stereo AUX Selector, 4 Input 1 Output / 1 Input 4 Output Splitter, Switcher Box With 4 Channel Switch Knob, No External Power Required

Love this small 4-port 3.5mm switch! Works flawlessly! I had 3 audio devices I kept interchanging between manually using same ear-buds. This small switch handles it all (with one more port available for later!). Easy operation, and the volume control is a big-plus! If one audio device is louder than the other, can easily adjust the volume from the switch itself. No distortion and no 'scratchiness' sound when adjust volume.

This works great and carries the audio well, letting me switch between two different sets of speakers and my headphones, and room for one more audio device. The only negative I have is the device has one input on the front, and all the other inputs on the back, which makes it a little awkward from a cable management perspective in some use cases. Nicely made, and a good value.

I regret buying this switch, I use it for work when I need to switch from my headphones to my speakers during multiple meetings. Well! It kind of does the job for meetings but the sound quality drops about 50% when I connect from PC to the switch. If you plan to listen to any music using this switch - forget about it, audio quality is horrible.

As a former AV professional I'm picky. This works great to switch audio sources between PC, iPad and phone at my desk while working remote. No noise, compact, and having the volume control is a nice bonus. Build quality seems good.

Does exactly what you would expect

I work from home and also have a personal computer at the same desk. Without going into my entire set-up, I have several audio sources that I wanted to go to the same listening source (my case, ear buds). Switching sources is as easy as turning a knob. The volume control is also a nice feature. Also, was very surprised (in a good way) how small it is. It doesn't take up much real estate on my desk. Good product.

It was a game changer when I first got it, I've been using it pretty much non-stop since I installed it in my desktop setup. I used to switch between my speakers and two different sets of headphones. It has failed at some point in the last month. I just noticed it thinking my headphones were broken, but the left channel on the main input no longer works. I took it apart and cleaned it and there is no physical damage visible to the board, the switches, or the audio jacks. It worked well but didn't last long enough.

I use 3 computers simultaneously and got tired of switching hdmi cables and the 3.5mm audio plug. I found hdmi switches that work great the only thing missing was a switch for the audio. This thing works perfectly. And it doesn't even require power. No audio quality issues whatsoever. Super easy to switch audio sources and even comes with a volume knob. There was no unpleasant sound while switching either. Couldn't be happier.
